Question

26.
If
f (x) = 2x3 - 13x2 + 17x + 12,
find the value of
f(-3)​

Answer 1

Answer:

f(2)=2×2

3

−13×2

2

+17×2+12

=16−52+34+12=10

f(−3)=2(−3)

3

−13(−3)

2

+17(−3)+12

=−54−117−51+12

=−210

Answer 2

Answer:

-210

Step-by-step explanation:

given

f(x)=2x3-13x2+17x+12

now, put x=-3

then,

f(-3)= 2×(-3)^3-13×(-3)^2+17(-3)+12

=2×-27-13×9-51+12

= -54-117-39

f(-3)= - 210
